WATCH: A Park Board commissioner is presenting an urgent motion to pull the plug on 4/20's musical headliner.

As debate rages around Vancouver’s 4/20 celebrations, critics are in agreement: booking Cypress Hill is a bridge too far.

Now Vancouver Park Board commissioner John Coupar plans to bring forward an emergency motion at Monday’s board meeting looking to cancel the veteran hip-hop group’s appearance at the pro-cannabis event.

The motion directs park board staff to contact the event’s organizers and urge them to “request a cancellation” in an effort to control of the size of the event, which Coupar says has gotten out of hand.

The announcement that Cypress Hill would be headlining this year’s 4/20 celebrations on Sunset Beach has reignited calls for organizers to face facts and declare themselves a festival, not a protest as they often call themselves.

Organizers, including Dana Larsen — who couldn’t be reached for comment following news of Coupar’s motion — argue the event protests several “unfair” aspects of cannabis legalization, including strict laws on public smoking and possession.

But Coupar is siding with critics who say the inclusion of paid vendors and sponsors proves the celebration has outstripped its protest roots and puts 4/20 at an unfair advantage compared to other sanctioned Vancouver events.

“What does it say to all of our other partners like Pride and Celebration of Light and Skookum that plays ball and does the right thing?” Coupar asked. “It just makes the whole civil government look foolish.”

Organizers of those events agree. They say it is unfair for 4/20 not to pay policing costs, which protests aren’t sanctioned to do, or obtain the proper permits.

“There is a difference between a protest, where you are showing up with signs and raising awareness about a political or important social justice , and having paid vendors and entertainers and a main stage. That is a festival,” Vancouver Pride Society executive director Andrea Arnott said Thursday.
